Abstract (en)
A composite laminated article is provided, useful for nted circuit boards in transmission of electrical signals in high frequency range of the order of 10 GHz, comprising ayer of expanded, porous polytetrafluoroethylene (PTFE), dntained in a fully stretched state, affixed firmly to a solid pstrate layer. The composite is formed by stretching ex- ded, unsintered PTFE in this fully stretched state, and nding the stretched PTFE to a susbstrate. The porous PTFE er in this composite has unexpectedly high compression istance.
